LUBBOCK, Texas (AP) — Freshman Jahmi’us Ramsey scored 18 points while making four 3-pointers and No. 22 Texas Tech pulled away for an 85-50 win over Oklahoma State to open Big 12 play Saturday.

The Red Raiders (10-3, 1-0 Big 12) went ahead to stay with 11 points in a row late in the first half. After Lindy Waters III made a jumper for Oklahoma State right after halftime, Texas Tech scored 15 in a row, with Ramsey hitting two 3s before his run-ending two free throws made it 51-32 with 15 1/2 minutes left.

TJ Holyfield added 17 points for the Red Raiders, while Davide Moriette and Terrence Shannon each had 13. Chris Clarke had 10 rebounds.

Waters had 13 points and was the only player in double figures for the Cowboys (9-4, 0-1), who shot 29 percent (15 of 52).

Waters had his jumper after halftime and two 3-pointers before another Oklahoma State player scored in the second half. It was 70-41 when Johnathan Laurent made a 3-pointer with just over seven minutes left.

Avery Anderson’s jumper with 6 1/2 minutes left in the first half put Oklahoma State up 26-25. Two free throws by Moretti started the Tech run. The Cowboys, meanwhile, missed five shots in a row and seven of eight to end the half.

BIG PICTURE

Oklahoma State: The Cowboys made five 3-pointers in the first 12 1/2 minutes, eerily similar for Texas Tech to a game last season when Oklahoma State made 17 of 32 from long rang. But the Pokes made only four more the rest of the game. … The Cowboys struggled in their previous losses with Isaac Likekele not playing. But they were at full strength for the conference opener and slipped badly.

Texas Tech: Strong starts have been rare in Lubbock but Texas Tech did just that to begin the first and second halves. They have won five games in a row, starting with the win over then top-ranked Louisville in New York. Clarke continues to impress off of the bench and Chris Beard expects his team will only be as good as the Virginia Tech transfer performs.
